 459  
 460  A module (or vector space) that is all the linear combinations of the 
 461  free module elements (or vectors) with scalars from the 
 462  ring (or field) given by ``base_ring``. See the examples below 
 463  describing behavior when the base ring is not specified and/or 
 464  the module elements are given as lists that do not carry 
 465  explicit base ring information.
